From Shrinkage to Decomposition: Understanding the Thermal Behavior of Battery Separators
English
Battery separators play a critical role in the safety, durability, and performance of lithium-ion batteries. When exposed to elevated temperatures or abusive conditions, they must maintain their structure to prevent internal short circuits and support safe battery operation.
In this webinar, we will show how thermogravimetric analysis coupled with mass spectrometry (TGA-MS) and thermomechanical analysis (TMA) provide valuable insights into the Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability, Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition behavior, shrinkage, and mechanical integrity of modern separator materials. Based on practical measurement examples, participants will learn how different separator types respond to thermal StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress and how this knowledge supports material selection, quality control, and safer battery design.
What Participants Can Expect
- Battery separator basics: why separators matter and what can happen at elevated temperatures
- TGA-MS insights: moisture release, Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition behavior, and evolved gas analysis
- TMA results: shrinkage, dimensional stability, and loss of mechanical integrity
Join the webinar and learn how thermal analysis helps evaluate battery separator safety before critical failure occurs.
